Test Coverage Comparison

Tool for displaying code coverage according to different measures. Accepts a JS function and any combination of input variable values.

Example

Download repo from Github and manually copy the only file and add the only dependency to you project. The the following minimal example should display a statement coverage in percentile.

var testCodeCoverage = require("./index.js");

var code = `
function code(a, b, c) {
    if(b<c){
      if(a<c){
      }
    }
    return;
}
`;

var testCases = [{a: 1,b: 1,c: 1}]

var tester = new testCodeCoverage.testCoverageComparison(code, testCases);

console.log(tester.statementCoverage());

Limitations

Currently only supports if blocks and logical operators.

TODO

Still WIP

Analysis targets

• Assignment operator
• Else blocks
• Increment operator
• While blocks

Algorithms

• Test runner should use the shadow tree pointers.
• Parser should be divided into smaller objects to allow finer grained output.

Testing

• Needs testing
